let’s take 7zip as example, first I tested the location on a testing PC, found that the location is C:\Program Files\7-Zip\,

@echo off

set Deploysoftware=\\path\to\the\7zipmsifile
if exist "%programfiles%\7-Zip\7zFM.exe" goto _End

Pushd "%Deploysoftware"
MSIEXEC.exe /i "7z1700-x64.msi" /q
echo "installation completed"
popd
